Below C Level
What do we have available before a C standard library and compiler toolchain are available? and what does it take to build those for the first time.
- Assembly. This seems like a useful resource.
- Forth. For example, Collapse OS, StoneKnifeForth, Reva Forth, Okami.
- A simpler C-like. Mu is like C with Basic-like statements. C4 should be easy to translate by hand to Assembly. C-- is a portable Assembly language. PicoC is a C interpreter.
